These survey-grade deliverables are ready for direct input into computer aided design (CAD) software packages such as AutoCAD, Civil3D, Magnet Office, Vulcan and BricsCAD. Standard topographic outputs from the Virtual Surveyor software are Surfaces or TINs (Triangular Irregular Network), Contours, and Line Surveys. “The software accomplishes this in a fraction of the time of a full field survey.” “The appeal of Virtual Surveyor is that it combines the interpretation skill of a professional surveyor with computing power to create standard survey products,” said Virtual Surveyor Managing Director Tom Op ‘t Eyndt. In a typical application, the Virtual Surveyor suite takes the orthophotos and digital surface models (DSM) extracted from UAV imagery with photogrammetric software like Pix4D or DroneDeploy and generates an interactive virtual environment onscreen where surveyors can apply their core skill to select the survey points and breaklines that define topography. Now used in 46 countries, Virtual Surveyor bridges the gap between UAV photogrammetric processing software and engineering design packages.
